Brian, are you going to provide TF with some feedback on the head porting? Be interesting to see how well they understand the cam timing sensitivity. I'm not sure if that is a feature or a bug to them. I think it is a bug for racers although it might be a feature for street guys.

I didn't have the capability of porting the heads so I had to make my changes with the cam. Between Dwane and myself we found a solution. I was surprised at how sensitive the TF heads were to cam timing and lobe profile. If you don't get the right combo the heads aren't happy
